 This behavior is enabled by default for most Lambda runtimes when using LocalStack Pro.
 
 Assuming you had a Python Lambda handler that attempts to list all S3 buckets. In the past, you had to manually configure the `endpoint_url` parameter on the boto3 client (and potentially use environment switches for dev/prod in your test code):

 ```
 
 With the patched AWS SDKs, it now becomes possible to deploy your unmodified production code to LocalStack, simply creating a boto3 client with default settings. The invocations of the boto3 client will be automatically forwarded to the local APIs:
